PlayStation 4 dev idc released new scripts on Github that invoke the PS4 kernel to decrypt the contents of a PS4 update file (firmware) and pup unpacker scripts, now before you ask no this release is not going to get you any steps closer to a PS4 CFW but as zecoxao outlines on his twitter this can help "porting webkit exploit everywhere, for instance. you can decrypt any usermode elfs from 1.00 to 3.55/3.70 because sony forgot to change keyset",
PuP Decryptionpup_decrypt: A utility to invoke the PS4 kernel to decrypt the contents of an update file. The default (hardcoded) operation is to decrypt /mnt/usb0/PS4UPDATE.PUP. This will output a number of files (depending if a normal or a recovery update):
These decrypted updates can then be further unpacked using a tool capable of doing so.
Note The PS4 will refuse to decrypt updates in some cases: Versions older than the installed version (for the most part, there's exceptions for things like beta versions).
Versions for a different product code (retail cannot decrypt test or debug updates)

pup_unpack A utility to unpack PS4 update blobs that have been previously decrypted using pup_decrypt.
Note This utility will not unpack the contents of nested filesystems. The filesystem images in updates are FAT32, exFAT, etc images and can be mounted or unpacked with other tools.

- Q (via twitter): What could this lead to ?
- A (via zecoxao): porting webkit exploit everywhere, for instance . you can decrypt any usermode elfs from 1.00 to 3.55/3.70 because sony forgot to change keyset
- Q (via Twitter): Is the first step to actual CFW, is there a way to repack and encrypt the PUP again?
- A (via zecoxao): no and there never will be unless you own a 15 million dollar quantum computer
